Abstract

A display structure having a high-brightness diffuse reflector, an electrowetting display structure based on the display structure, an in-cell type electrowetting display structure and a manufacturing method thereof are disclosed. The display structure comprises panel glass ( 1 ), a display layer ( 2 ) and substrate glass ( 3 ), wherein a high-brightness diffuse reflection polymer thin film material ( 4 ) is arranged under the substrate glass ( 3 ); the panel glass ( 1 ), the display layer ( 2 ), the substrate glass ( 3 ) and the diffuse reflection polymer thin film material ( 4 ) are stacked in sequence. According to the display structure and manufacturing method thereof of the invention, the required diffuse reflection and contrast ratio approximate to paper can be provided by placing a high-brightness diffuse reflection polymer thin film under a substrate or a display layer of a plate display structure as a diffuse reflection layer or a diffuse reflector.

Claims (17)

1. A display structure with a high-brightness diffuse reflector, comprising panel glass, a display layer and substrate glass, wherein

the reflector is made by a diffuse reflection polymer thin film material, wherein the diffuse reflection polymer thin film material is a PET-based material with a thickness of 175-350 μm,

the panel glass, the display layer, the substrate glass and the reflector are stacked in sequence, and

the reflector is arranged under the substrate glass,

wherein the substrate glass has a thickness of less than 0.2 mm to reduce a light path between the display layer and the reflector;

an adhesive layer is arranged between the substrate glass and the diffuse reflection polymer thin film material, which is used for adhering the diffuse reflection polymer thin film material to the substrate side of the display structure; and

an optical property of the adhesive layer enables incident light and emergent light to penetrate through the adhesive layer.

2. The display structure with a high-brightness diffuse reflector according to claim 1 , wherein the diffuse reflection polymer thin film material is filled with diffuse reflection particles allowing a diffuse reflection to incident light of the display structure.

3. An electrowetting display structure, using the display structure with a high-brightness diffuse reflector according to any one of claims 1 or 2 , wherein the display layer is an EFD switching layer.

4. A method for manufacturing a display structure with a high-brightness diffuse reflector, comprising the following steps:

arranging a display layer on the substrate glass, wherein the substrate glass has a thickness of less than 0.2 mm to reduce a light path between the display layer and the reflector;

arranging panel glass on the display layer;

arranging an adhesive layer at one side of the substrate glass away from the display layer; and

arranging a reflector at one side of the adhesive layer away from the substrate glass, wherein

the reflector is a diffuse reflection polymer thin film material which is a PET-based material with a thickness of 170-350 μm, and an optical property of the adhesive layer enables incident light and emergent light to penetrate through the adhesive layer.

5. The method for manufacturing a display structure with a high-brightness diffuse reflector according to claim 4 , wherein

the diffuse reflection polymer thin film material is filled with diffuse reflection particles allowing a diffuse reflection to incident light of the display structure.
